First solids …

Kate

My baby is almost 6 months old and I’m looking to introduce her to solids. Going to start with purées first but I’m not sure where to begin; should I start with the earths best organic oatmeal ? A veggie? When and how much do I feed? Do I start once a day at dinner time? Breakfast? Does it matter? Also wondering if starting solids helped baby sleep better. My daughters been waking up every 2 hours for the past almost 2 months. ? Thanks guys!
